Charge initiated lightning protection system for a wind turbine blade and wind turbine blade with the charge initiated lighting protection system

Abstract

A lightning protection system is provided for a wind turbine blade via charge initiation (Charge Initiated Lightning Protection). The lightning protection system includes at least one electric charge generator for generating electric charge at a lightning receptor of the wind turbine blade such that an electrostatic field is generated at the lightning receptor leading lightning current directly to the lightning receptor. Additionally a wind turbine blade having at least one such lightning protection system is provided.
